| Review (by Malcolm Storey) | This was the first widely available informal guide to some of our more difficult groups of vascular plants. Although the groups selected were those found in Watsonian Vice-counties 66-70 (Durham, Northumbria and Cumbria) it is useful throughout Britain. Consists of a large number of type-written accounts of various genera or small groups of species which are difficult to identify. The accounts are by a variety of specialists, many previously published elsewhere, but the present work brings them together. Superseded by various editions of the "Plant Crib", but still sometimes useful for a different view, additional illustrations or groups not covered in later publications. |
| Errata, Corrigenda & Comments | A list of errata appears in Plant Crib 1988 (page 139). |
